How to Tell if Your Alternator is Bad

What are the signs of a failing alternator? Because the alternator turns mechanical energy into electrical energy, it has a hand in a number of essential car functions. That means that a driver in Stephenville might notice strange noises, while a driver in Eastland might notice electrical problems – so proper diagnosis is key! Here are some common signs of a bad alternator:

• Dim Lights: Dim or flickering lights is one of the most common signs of a failing alternator. Many drivers notice a dimness in their headlights, but this can also affect your dash lights or center dome light. If revving the engine makes your lights brighter, this points to the alternator even more.
• Dashboard Lights: A failing alternator will likely trigger at least one of your dashboard lights. Most people notice a red battery icon that won’t turn off, but some get a “Check Engine” or “ALT” light instead.
• Unusual Noises: Strange noises under the hood are always worth a trip to the service center. Some people notice a squealing noise from the serpentine belt or a grinding noise if the internal bearings have worn out, both can result from alternator issues.
• Electrical Problems: The alternator has a huge role in your car’s electrical system. You may notice your electrical systems slowing down or stopping completely: sluggish power seats, radio turning off, windows failing to roll down.
• Battery Dying: When the alternator goes, your car will use up your battery’s power without the ability to restore its charge. If you change your battery and it dies instantly, this is one of the major signs of a bad alternator.
